Abstract
A printing data transmitted from a host computer is stored in a receiving buffer. An editorial unit receives the printing data in the receiving buffer in each one line and writes into a page buffer after compressed. An expansion unit reads out the printing data in the page buffer and deploys them into a band buffer as a raster data. An engine unit performs printing in accordance with the raster data in the band buffer. The editorial unit compresses the printing data of each line up until the preset line N with plural types of compression techniques and computes compression rates for each line. A compression technique to be applied is determined in accordance with the compression rates. The printing data of each line up until those of the preset line X are compressed by the determined compression technique. A determination of the compression technique is repeated in every completion of the printing data processing for the X lines.
